Substitute $3$ for $x$ and substitute $- 2$ for $y$ in the other equation and determine if the equation is valid.

$\text{see explanation}$
$\text{by substituting "(3,-2)" into the equation}$
$\text{that is substitute x = 3 and y = -2 into the equation}$
$\text{if the equation is true for these values then it is satisfied}$
